Abstract:
Objective To compare the influence of regular intermittent bolus of different con-centrations of ropivacaine for epidural labor analgesia on maternal intrapartum fever.Methods One hundred parturients aged from 20 to 35 years,of ASA Ⅰ or Ⅱ,singleton pregnancy,head presenta-tion,were randomly divided into two groups:Group H with 0.1% ropivacaine and 0.4 μg/ml sufen-tanil,Group L with 0.08% ropivacaine and 0.4 μg/ml sufentanil,50 cases in each group.Both groups were given epidural analgesic solution of 8 ml every 60 minutes respectively.Maternal tympanic membrane temperature,pain visual analogue scale (VAS),and modified Bromage score were recorded at the beginning of analgesia,1,2,3,4,5 h post analgesia,delivery,and 1 h post de-livery.And the anesthetics consumptions,labor duration,and neonatal Apgar score of 1,and 5 min were also observed.Results Compared with the beginning of analgesia,maternal tympanic membrane temperature significantly rose at 4,5 h post analgesia,delivery,and 1 h post delivery in both groups (P <0.05).Compared with group L,maternal tympanic membrane temperature significantly rose at 4,and 5 h post analgesia in group H (P <0.05).There was no significant difference in the incidence of intrapartum fever between the two groups.Compared with the beginning of analgesia,maternal VAS significantly decreased from 1 h post analgesia to 1 h post delivery in both groups (P <0.05);but there was no statistically significant difference between the two groups.Conclusion Regular inter-mittent epidural bolus of 0.08% or 0.1% ropivacaine combined with 0.4 μg/ml sufentanil can provide satisfactory labor analgesia,and body temperature rises more dramatically in women receiving higher concentration of local anesthetic than those receiving lower concentration.
